Replacing the RAID Battery Backup Unit

This section pertains only to the MARS 110R, 110, 210, GC2R, and GC2 appliances.

RAID Controller Back-Up Battery
Part number: CS-MARS-X10-BB=

The RAID Backup Battery Unit (RAID BBU) prevents RAID data loss by preserving data held in the RAID cache module during a power outage. The RAID BBU can provide up to 72 hours of battery power until the system power is restored.

The RAID BBU requires 24 hours to fully charge from when the appliance is first powered on, and is continually charged thereafter from the system power. The total charge capacity of the battery degrades over time. The show healthinfo CLI command reports the relative charge state of the RAID BBU.

There is a direct relationship between the relative charge and the battery backup time
(100%charge = 72hours). A 100 percent charge provides 72 hours RAID cache protection. Similarly, a 75 percent charge provides 54 hours of protection (100%charge * .75 = 72hours * .75).

Make sure there is sufficient charge to provide RAID cache protection for the total probable hours the MARS Appliance could be without system power. For example, a 90.3% charge (65 hours) would allow 2 hours to manually restore system power if a total power outage occurred in an unattended facility between 17h00 Friday to 8h00 Monday (63 hours).

Example 5-1 displays BBU status information in an excerpt of the show healthinfo CLI command.

Replacing the System Battery

This section pertains only to the MARS 110R, 110, 210, GC2R, and GC2 appliances.

The lithium battery on the appliance board can power the system real-time clock for up to 10 years in the absence of power. When the battery starts to weaken, it loses voltage, and the appliance settings stored in CMOS RAM (for example, the date and time) may be wrong.

If the system battery of the MARS Appliance fails contact Technical Support for replacement procedures.

Warning

There is the danger of explosion if the battery is replaced incorrectly. Replace the battery only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions. Statement 1015

Note Hard drives can consume up to 17 watts of power each. Drives are specified to run at a maximum ambient temperature of 45 °C.

Hard Drive Status LEDs

Each HDD has a status LED. A flickering green light indicates activity. The control panel has a status LED that flickers with any HDD activity.

Partition Checking

The appliance automatically runs checks on HDD partitions after the system has been re-booted 25-30 times, or if the appliance has not been re-booted in 180 days.

Overview of RAID Subsystem

This section pertains to the following MARS Appliances equipped with a Serial ATA RAID
controller card:

•CS-MARS-55-K9

•CS-MARS-110R-K9

•CS-MARS-110-K9

•CS-MARS-210-K9

•CS-MARS-GC2R-K9

•CS-MARS-GC2-K9

Except for the MARS 55, the MARS RAID controller cards operate the hard drives in a RAID 10 configuration, also called RAID 1+0 because it combines the data handling techniques of RAID 1 and RAID 0. The MARS 55 operates as RAID 1 only. For additional information on RAID concepts and terminology, access the following URL: http://en.wikipedia.org/wiki/RAID

RAID 0 Data Striping

In a MARS RAID 10 configuration, half the total number of drives are arrayed as a single logical drive, wherein a data block is distributed across all of the physical drives in the logical drive using RAID 0 striping techniques. Data striping results in better performance for a data intensive application such as MARS, because hard drive random access times are minimized when data is read and written simultaneously from more than one physical hard drive.

Note The MARS 55 does not do RAID 0 striping. It is RAID 1 only.

RAID 1 Mirroring and Subunits

Half the number of drives in the MARS RAID 10 array mirror the RAID 0 virtual drive. Each physical drive in the RAID 0 array is mirrored by an identical physical drive using RAID 1 techniques. Data written to one of the drives within the RAID 0 array is simultaneously written to its dedicated RAID 1 partner, thereby providing fault tolerance through data redundancy. The RAID 1 hard drive pairs are listed in Table 5-4. For the MARS 55, one drive mirrors the other in a simple RAID 1 configuration.

Rebuilding a Degraded Array

Either drive in a RAID 1 pair can serve in place of its partner should either drive become degraded (unavailable, physically inoperative, or data corrupted). A physical drive degraded but still physically operative can be rebuilt from the data of its undegraded partner and rejoin the array. An inoperative physical drive can be replaced with an operative one which is then rebuilt to join the array.

When any physical drive of the RAID 10 array is degraded, the entire array is considered degraded. While the array still functions, it is not working to its optimal throughput or redundancy capacity.

In a degraded RAID 10 array, data destined for a degraded physical drive is written to available space on the RAID 1 partner until the degraded drive can be rebuilt or replaced. Degraded drives are rebuilt in sequence, one rebuilding process must complete before the next process can begin. Between 200 and 300 minutes are required to rebuild a RAID 1 subunit.

Hotswapping Hard Drives

This section pertains only to the MARS 55, 110R, 110, 210, GC2R, and GC2 appliances.

An HDD can be hotswapped, that is, replaced without rebooting the MARS appliance. The hotswap actions can be summarized in the following five steps. The detailed procedure is in the section, Procedure to Hotswap a Hard Drive.

1. Establish a console connection to the MARS appliance.

2. Enter the raidstatus command to determine the status and the chassis HDD slot number of the HDD to hotswap.

3. Execute a hotswap remove disk command, then remove the HDD.

4. Execute a hotswap add disk command then insert the replacement HDD.

5. Enter the raidstatus command to monitor the progress of the replacement HDD as it is rebuilt.

Use the raidstatus CLI command to view the status of the RAID array (virtual disk) and of the individual HDDs. Table 5-2 lists the status conditions that require an HDD to be hotswapped. These status conditions cause MARS to send an email alert to the administrator.

Caution Always use the hotswap remove disk CLI command before you remove a hard drive and
hotswap add disk before you insert a hard drive. The disk argument is the hard drive slot number.
Use the hotswap list all command to view the slot number to Port and PD number map.

The rebuilding process duration is between 200 and 300 minutes, depending on CPU load.

Note To match original performance, hotswapped HDDs should be the same make, model and size as the original HDDs.

Caution The RAID 10 array will not function if both HDDs of any RAID 1 pair are removed or corrupted.

Procedure to Hotswap a Hard Drive

This section pertains only to the MARS 55, 110R, 110, 210, GC2R, and GC2 appliances.

In the hotswap command, the disk parameter is the chassis slot number of the HDD, but the raidstatus command reports physical drive (PD) numbers or Port numbers (MARS 55). To determine the physical location of the slot in the chassis (chassis slot number), see Figure 5-7 or Figure 5-8 or use the hotswap list all command.

To hotswap an HDD, complete the following steps:

Step 1 Remove the front bezel. See the "Removing and Replacing the Front Bezel" section.

Step 2 Establish a console connection with MARS.

Step 3 Identify the slot number of the HDD to replace with the raidstatus command.

Step 4 Enter hotswap remove disk. (where disk is the slot number of the HDD)

A message informs you that it is safe to remove the HDD.

Note Make sure that you remove the correct physical HDD. If you remove the wrong one accidently then reinsert it, that HDD will register as Unconfigured Good (or Failed for MARS 55).

Step 5 Pull out the black lever of the hard drive carrier and slide the carrier from the chassis as shown in callout B of Figure 5-9.

Figure 5-9 Removing a Hard Drive from the MARS Appliance Chassis

The raidstatus command should now report the slot status as N/A (or Failed for MARS 55).

Step 6 At the CLI prompt, enter hotswap add disk. Be sure to use the same slot number as in Step 2.

Step 7 With the black lever in the fully open position, slide the replacement HDD and carrier into the chassis. The green latch at the front of the drive carrier must be to the right. Do not push on the black drive carrier lever until the lever begins to close by itself.

Step 8 When the black drive carrier lever begins to close by itself, push it closed to lock the drive assembly into place.

A console message informs you that the HDD (disk) is added successfully (to the logical array).

Step 9 Replace the front bezel. (See "Removing and Replacing the Front Bezel" section).

Step 10 From the CLI, enter raidstatus to verify that the HDD is being rebuilt into the RAID array.

The status message indicates the progress of the added HDD.

The rebuilding process can last from 200 to 300 minutes.

End of Procedure, Hotswapping Hard Drives.

Diagnostic Beep Codes

Table 5-5 lists Power-on Self Test (POST) error beep codes. Prior to system Video initialization, BIOS uses these beep codes to signal error conditions. The beep code is followed by a user visible code on the POST Progress LEDs (not shown). Beep codes are sounded each time the problem is discovered, such as on each power-up attempt, but they are not sounded continuously. The beep code sequence is read left to right. For example, 4-7 represents four beeps followed by seven beeps.
